IMPULSE VOLTAGE TEST SYSTEM
Category : Electric Equipments
|
Application
GIV series impulse voltage test systems can be used to generate impulse voltages simulating lightning impulse (1.2±30%/50±20%μs), chopped lightning impulse, switching impulse (250±10%/2500±10% μs) and steep front waveforms.
With special design, they can be used to test large capacitance electrical apparatus, such as GIS and cables.
With small inductance, they can be applicable for testing the large capacity transformers.
The generator carries out specific tests for industry and research applications.
Standard
IEC60060-1, IEC60060-2, IEC62177, IEC61109, IEC61211, IEC60099-4, IEC60076-3, other national standards and specific technical standards
Advantages and Features
(1) Reliable and accurate triggering by improved Marx circuit.
(2) With wave shaping resistors for lightning impulse, switching impulse and chopped waveforms.
(3) With the possible lowest internal inductance.
(4) Sealed spark gaps with filtered air-flow.
(5) With impulse capacitors of no PCB, low inductance and long service life.
(6) Automatic earthing device for personnel and equipment safety.
(7) A long service life is ensured.
(8) Over-voltage protection, over current protection and fast voltage transients protection.
(9) Stable and precise communication between the measuring system and control system.
(10) Reliable and precision controlled triggering unit by power pulse
(11) Easy operation with the console based on PLC module.
(12) With optical-fiber for high reliability
